Built from the ground up with industry-leading functionality, the ROMEO-X reflects their experience in developing durable red-dot technology trusted by the military and now available in a streamlined civilian package. Featuring a CNC 7075 aluminum housing, intuitive adjustment buttons, a side-mounted battery compartment, and an ultra-low deck height that allows co-witness with standard iron sights. Designed, tested, and assembled in the USA, the ROMEO-X offers direct mounting footprints compatible with your favorite optics-ready pistols. This model uses the RMSc mounting footprint and accepts CR1632 batteries. Included with each optic is a set of mounting screws, torx wrenches, and a free CR1632 battery.
